Well, this is a topic that every chicken owner needs to address, even if you don't plan on dispatching chickens for your table. Sometimes you'll have a bird that is so sick or injured that it needs to be helped Across The Road for their own benefit. And sometimes you have birds that are causing trouble with the rest of the flock or with its humans.
Many folks will happily dispatch an aggressive rooster and make a meal of him. If you can't or don't want to do that it's okay. You can find someone in your area who would welcome your unwanted birds for that purpose. Otherwise, figure out what method you can manage, and bury the bodies as fertilizer for some fortunate plants.
Try covering the bird's face with a sock so you aren't seeing its eyes as you kill it.
